5.0 CONNECTING THE HARDWARE
• Turn off equipment that will be connected to the matrix. Mount the matrix in an
equipment rack if desired, using the included rack ears. Otherwise, place the
matrix on a flat surface with adequate ventilation and access to the front and
rear panels.
• Connect an HDMI approved cable from each HDMI source to an input of the
matrix. Cable lengths should be kept as short as possible.
• Since HDMI connectors can sometimes become loose, use locking HDMI
cables or mount the matrix to a flat surface and add strain relief tie-downs a
few inches away from every HDMI cable connector.
• If using locking cables, remove the Phillips screws above each HDMI port and
replace them with the hex-head jack screws provided. Plug in the HDMI cable
and insert the cable screws into the jack screw heads.
• Connect the outputs of the matrix to their destination devices.
• If you are using the infrared extension function, connect the extension IR
sensor cable and position the sensor.
• Connect the power adapter to the AC source and then to the matrix. Twist the
DC plug to 90 degrees in the matrix power port to lock.
• If you are using the RS-232 control function, connect an RS-232 cable with
pinout as shown below.
